Avril Lavigne is clearly Cassadee Pope’s inspiration, and dreams came true when they sang “I’m With You” together on The Voice Season 3 live finale tonight, Dec. 18, 2012.It was hard to distinguish between the two rockers’ similar voices, both belting the notes in coordinating black and silver outfits. Cassadee looked overjoyed to perform with her “hero,” and they grinned adorably at each other throughout the song, even clasping hands and jumping up and down when they were done. Aww! We think it’s about time for Avril to make a comeback, and what better way to do that than forming a duo with Cassadee? Jussayin’.What did you think of this performance? Tell us below!
